CRL-U.S. Aluminum is pleased to introduce the new NFRC-rated ArcticFront Series 45X Storefront! The system delivers optimal thermal performance with the installer-friendly design of a traditional 2" x 4-1/2" storefront.
The key feature of the ArcticFront 45X is its dual polyurethane thermal break points that act as a superior thermal barrier.This allows you to attain U-factors as low as 0.37 using standard low-E glass, and 0.19 using specially configured insulating glass units.
For peak performance, use the ArcticFront 45X Storefront in conjunction with CRL-U.S. Aluminum’s Series 375-T High Performance Medium Stile Thermal Doors. Also NFRC rated, the doors are thermally broken utilizing 20 mm struts.
